    Now looking at the graphs... which one has a domain where x=>0 ? Note that domain means all the possible x-values that a function can have. SO if x=>0 , this means that x has to be EQUAL to 0 or greater

    not quite.. if you look at the parabola sketch, you can see that there are negative values for x... |dw:1433302946456:dw| Look at your x-axis (which i have labelled for you). Which one has NO x-values after x = 0? So which graph has no negative x values?
